History of the Peloponnesian War

For though born long after the Trojan war, yet he gives them not anywhere that name in general, nor indeed to any but those that with Achilles came out of Phthiotis and were the first so called; but in his poems he mentioneth Danaans, Argives, and Achaeans. Nor doth he likewise use the word barbarians; because the Grecians, as it seemeth unto me, were not yet distinguished by one common name of Hellenes, oppositely answerable unto them.

The Grecians then, neither as they had that name in particular by mutual intercourse, nor after, universally so termed, did ever before the Trojan war, for want of strength and correspondence, enter into any action with their forces joined. And to that expedition they came together by the means of navigation, which the most part of Greece had now received.

For Minos was the most ancient of all that by report we know to have built a navy. And he made himself master of the now Grecian Sea, and both commanded the isles called Cyclades and also was the first that sent colonies into most of the same, expelling thence the Carians and constituting his own sons there for governors; and also freed the seas of pirates as much as he could, for the better coming in, as is likely, of his own revenue.
